ANKLES

Question 1

LAT
bisection of talus and 1st met
intersect at apex of deformity

Answer 1

Meary’s angle

Question 2

LAT
long axis of calcaneus and bisection of 1st met
intersect at apex of defomity

Answer 2

Hibbs angle

Question 3

increased calc inclination angle 35-40 degrees

increased met declination angle 25-35 degrees

hammertoe deformities

Answer 3

LAT

Question 4

meary’s angle intersects at base of 1st met and lisfrancs joint

• meary’s angle>10
• calc inclination<30

Answer 4

anterior cavus foot

Question 5

meary’s angle intersects proximal to choparts joint

meary’s angle>10

calc inclination <30

Answer 5

anterior cavus foot

Question 6

meary’s angle intersects proximal to choparts joint

meary’s angle < 10

calc inclination > 30`

Answer 6

posterior cavus foot

Question 7

meary’s angle intersects at NC joint and >10

dynamic cause extensor substitution (tight posterior group)

calc inclination > 30 = post cavus and <30=anterior cavus

Answer 7

mid foot cavus

Question 8

what are the important ST procedures?

Answer 8

steindler stripping
jones suspension
Hibbs suspension
peroneal stop
Tibialis posterior tendon transfer
split tibialis anterior tendon transfer
